  • In CTAG BEAST Assembly help

    Hello!
    I recently purchased a CTAG BEAST Starter Kit (https://shop.bela.io/collections/multichannel/products/ctag-beast-starter-kit) and I'm having some trouble assembling it/stacking the units. Are there any instructions? They seem to be improperly configured to me... Do I need to move around the jumpers and plastic connectors for them to stack properly?

    I assume one CTAG should have the jumper set to master, the other to slave? Now they're both masters. Should the master be at the bottom, connecting to the BeagleBone, or does it not matter?

    On one of the CTAGs, there's a 2 pin connector called "Beast". On the other, there are 4 pins in the same place, covered with a little plastic socket connector. The backsides also have these – but they seem to be in the wrong place in order for me to stack them. Now pin meets pin, rather than pin meets socket.

    thanks for the help!

    giuliomoro great, thank you. good idea to try it mixed down to stereo first.

    • In Pd: disabling loop in playAudioFile~

      giuliomoro [readsf~]

      thank you so much! this solved all my problems. the final patch ended up a lot less complicated than my first endeavours and now it all runs smoothly.

      follow up question: i'm working on a future project with the ctag beast, where it will be used as a simple wav file player. it's a 16 channel sound piece, with audio files are that are just under an hour long.
      do you reckon i can use the readsf~ object to handle this as well? or would that be too much data to stream from the sd card?

      thanks again!

        • In Pd: disabling loop in playAudioFile~

          been working on this all day, and finally got it working the way i wanted to.
          however, now another problem has appeared : )
          my files seem to be too big. first i got truncate messages, then i changed maxsize in soudfiler, now it get "pd: resizebytes() failed -- out of memory
          error: resize failed".

          does the playAudioFile~ subpatch buffer audio in some way to work with bigger files? or would you recommend using c++ instead, starting with the sample-streamer example code? thanks for your time!

          giuliomoro hey, thanks a lot for your quick and detailed reply!
          however, i've removed the metro part from my patch, and it's still looping the wav file playback. this is what my main patch looks like:

            • In Pd: disabling loop in playAudioFile~

              hello,

              i’m new to bela and quite new to programming in general, and would love some help with a simple puredata patch i’m making. the problem i can’t solve is how to disable audio files from looping. i've tried to search for help and figuring it out myself, but i can't seem to get there.

              the project is a basic 4 channel installation, with a button that triggers four audio files. i’m using the bela mini with the multichannel expander.

              i’ve successfully combined two example patches that are provided in the ide – ‘examples/multichannel/pd-multi-sample-player’ and ‘examples/puredata/digital-input’ . the button works and plays the wav files, all routed to separate outputs as intended. however, they loop.

              looking in the playAudioFile~ object, i can’t quite make sense of it. any help explaining what makes them loop would be greatly appreciated!

              i've attached two screenshots, of playAudioFile~ and playRetrig:
